All-time basketball great Lauren Jackson has revealed she was on anti-depressants through her career in a revealing SBS documentary.
Some of Australia's most prominent athletes have opened up about the mental challenge of retirement in a new documentary series to air next week.
Four-time Olympic medallist and Opal Lauren Jackson and AFL star Barry Hall have spoken candidly of their battles with depression, while athlete Jana Pittman said she was yet to cope with having retired.
Each climbed to the summit of their chosen sport.
Jackson was a world champion with the Opals in 2006, and was named MVP four times in the WNBA.
Hall won the 2005 premiership with Sydney and claimed 11 club goalkicking prizes throughout his career.
Pittman claimed two hurdling world championship gold medals and four Commonwealth golds before becoming the first woman to compete at both the winter and summer Olympics.
And when their careers were over, each of them fell. Hard.
"Within five minutes, I was bawling," Jackson told SBS television program Insight.
"I went into a shell. I stayed with my parents and never left the house. They just took care of me.
"Without them I hate to think what might have happened."
Jackson said she felt abandoned by the same teams that supported her while she was playing.
"I felt like I was put out to pasture. I'd been one of their greatest resources and athletes and then all of a sudden it was over. You don't hear from them," she said.
"I was on anti-depressants during my career.
"You spend so much time doing that one thing and then all of a sudden it's over."
Hall - one of the most feared forwards of the modern era - said he was transformed in retirement.
"I had two or three months when I really struggled," he said.
"I didn't get out of bed. I didn't answer mates' phone calls. I was eating terribly and drinking heavily. It was a tough time.
"I didn't know it at that stage but that was a form of depression.
"I didn't know anything about it because we're big tough burly men that don't get depressed ... but it's a real issue in sport."
Pittman - whose athletics career matches up with the modern-day Australian greats - said she struggled as a result of not meeting her own expectations.
"I'm not sure I've actually coped with (retirement) yet," she said.
"It's the hardest thing I've ever done.
"I never hit the goal that I was hoping for in my career.
"Growing up as a child wanting to win in the Olympic Games was all I ever dreamed of ... I never made it.
"I can't let go because that elusive gold medal never happened."
The interviews are part of a two-part series to screen on April 11 and 18.
